The following system has been running fine for two years:
GA-EP45-UD3R rev 1.0 BIOS v 11
2 GB RAM GSKILL PC-6400 4-4-4-12
ANTEC 550W Trio
EVGA 9800 GT Nvidia, with latest drivers
XP SP3
Trend Micro AV/Security
Problem - system makes it through POST, but hangs during windows startup.
System is dual boot, separate disks, both XP SP3. Neither OS will start up in dual channel.
The system *will* start all the way if in "Safe Mode with Networking".
I removed the NVIDIA card and replace with ATI 4550 - SYSTEM HANGS
Conclusion - video card not problem.
I have 2 GB memory, in two identical sticks.
Either stick by itself in DDR2-1 - STARTUP SUCCESSFUL
Conclusion - memory not bad.
One stick in DDR2-1 and other in DDR2-3 - SYSTEM HANGS
One stick in DDR2-2 and other in DDR2-4 - SYSTEM HANGS
Put one stick in DDR2-1, other in DDR2-2 - STARTUP SUCCESSFUL (single channel mode)
Conclusion - there is some problem with running in dual channel in normal mode.
Any ideas/suggestions?
Thanks,
Ed
